Mine: Seeing how my computer desk is on the wall between my garage so you put a small fan in the garage plug it in have it connected by alluminum hoes like super glue it or sumthing i don't know what there called but those things are are commonly found next to washer machines and stuff. Cut a neat tight hole in the wall and put the hoes in it so it fits tight no holes or you will be cold. Get a case and cut a hole in the side of the case and cut a whole in the case and put it tight in the case hole glued and there you go instant air flowing in and it wont be loud because its in the garage.

yea i know its kind of etchy how i explained it but hey i only got so much time!

EDIT: BTW Musjunk a friend of mine has an AC unit propped up in his window. It's a little mini one meant for just a single room because his house's central air basically didn't work so his mom got one of these things for each of her kids in their rooms. Anyway my friends, if you left it on the coldest setting full blast would start to bog down because it would form ice crystals in itself lol and you had to turn on regular air to melt it a little.

i dont think taking the side of your case off helps very much, i tried it once and checked temps throughout it(cpu) went up 4 degrees idle when case side came off, then i put a big 18 inch fan beside my comp on high and it only went down 3 degrees... you got me/

Is this a good idea? OK it's almost winter and the temperatures are really cold and windy, maybe 40-50. My computer is next to the window and I have the window opened. I also took the case off the top of my PC.

I'm surprised no one's mentioned liquid nitrogen, even tho it's expensive and almost impossible to obtain if you're not a chem engineer...good thing my bro is ! Does seem a little irrational/over the top tho
